USB flash drives account for a large proportion of the data distribution and business promotion markets. Their capacity to hold a very large amount of data in such a small package makes them perfect replacements for CD and DVD discs.
Along with the fact that their prices are falling as mass production of USB sticks increases, they are now starting to become the choice format for many businesses that need to distribute very large files quickly, to existing clients or potential new ones, and also existing personnel. Just about everyone seems to possess at least one memory stick and they can be obtained in a vast array of shapes, sizes and colours.
